I'm getting consistent failures from
ndb/dns -rs
that look like this:
assert failed: rp->magic == RRmagic
The corresponding stack dump is:

It is likely that I have a consistency error in the database:
something along these lines, but not very clearly, was reported when I
tried to do a zone transfer from Plan 9 to NetBSD; I have not been
able to track the cause down.
Perhaps somebody here has a clue on how best to approach solving this
problem?
